2. Star a message

Starring a message creates a convenient way to go back to a phone number, address or article link a friend sent you. Long-press on the message, then tap on the Star icon.

To view your starred messages, on iOS select the Star tab along the bottom of your screen. Android users need to tap on the Menu button, then Starred Messages.

3. Who do you talk to the most?

Curious about who your BFF is on WhatsApp? If you have an iPhone, it's easy to figure out.

Go to Settings > Data and Storage Use > Storage Use. A list of contacts will populate, in order of who is using the most storage on your phone. Tap on each contact to view more detailed stats, such as the number of messages exchanged, images and GIFs.

Android users can go to Settings > Chat > Chat History > Email Chat to view the same info. Thanks to CNET reader CherryC22 for the tip.

4. Get message details

Ever wonder what time a message was delivered or read? Swipe to the left on a message you sent to view those stats on your iPhone. Android users can long-press on a message, then tap on the "info" icon at the top of your screen.

5. Mute a conversation

When heading into a movie or meeting, use WhatsApp's mute feature to silence a chatty group conversation or a friend who doesn't get the hint that you're busy.

Android users can long-press on a chat, then tap on the crossed-out speaker icon at the top of the screen. iPhone users need to open a conversation, then tap on the contact or group's name at the top of the screen followed by Mute.

WhatsApp provides the option to mute a chat from 8 hours to 1 year, which seems a bit like overkill.

10. Custom notifications

Instead of having the same alert sound for every incoming message, you can set custom alerts for individual contacts. Doing so will make it easier to know who messaged you without looking at your phone.

Android users should tap on the Menu icon when viewing a chat thread, followed by View Contact > Custom Notifications.

For those using WhatsApp on an iPhone, tap on the contact's name when viewing a chat thread, then Custom Notifications.
